First we find the measurement of dark dot .
ANd for that we have to use the formula of the angle formed by the intersection of chord .
Let the dark dot be t.
So we have
t and z are linear pair and sum of angles of linear pair =180 degree.
So we get
By measuring and knowing the wait of the ounces and height
Step-by-step explanation:
We know that,
1 m = 100 cm
the conversion from m² to cm² is as follows :
(1 m)² = (100 cm)² = 10000 cm²
A conversion factor between cubic meters and cubic centimeters is as follows :
(1 cm)³ = (100 cm)³
= 1000000 cm³
To convert m³ to cm³, multiply by 1000000.
Hence, this is the required solution.
Answer:
Systematic sampling
Step-by-step explanation:
An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.
For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10
He will have to select ; ( x / n )^th of the sampling frame for best results
